I have created a Transaction table with columns card_id, amount, created_at. There may be more than 1 row of one user so I want to return the value card_id, sum(amount), first created_at date of all users.
CREATE TABLE Transactions(card_id int, amount money, created_at date)
INSERT INTO Transactions(card_id, amount, created_at)
SELECT 1, 500, '2016-01-01' union all
SELECT 1, 100, '2016-01-01' union all
SELECT 1, 100, '2016-01-01' union all
SELECT 1, 200, '2016-01-02' union all
SELECT 1, 300, '2016-01-03' union all
SELECT 2, 100, '2016-01-04' union all
SELECT 2, 200, '2016-01-05' union all
SELECT 3, 700, '2016-01-06' union all
SELECT 1, 100, '2016-01-07' union all
SELECT 2, 100, '2016-01-07' union all
SELECT 3, 100, '2016-01-07'
I have created function for that but one of my client says I need query not function. Can anyone here suggest what query to use?
CREATE FUNCTION [dbo].[card_id_data]()
RETURNS #t TABLE
(
card_id text,
amount money,
dateOfFirstTransaction date
)
AS
BEGIN
INSERT INTO #t(card_id)
SELECT DISTINCT(card_id) FROM Transactions;
UPDATE #t
SET dateOfFirstTransaction = b.createdat
FROM
(SELECT DISTINCT(card_id) cardid,
MIN(created_at) createdat
FROM Transactions
WHERE amount < 0
GROUP BY card_id) b
WHERE card_id = b.cardid;
UPDATE #t
SET amount = T.AMOUNT
FROM
(SELECT
card_id AS cardid, SUM(MIN(AMOUNT)) AMOUNT, created_at
FROM Transactions
WHERE amount < 0
GROUP BY card_id, created_at) T
WHERE card_id = cardid
AND dateOfFirstTransaction = created_at;
RETURN
END
I want a result as shown in this screenshot:
You can use DENSE_RANK for this. It will number the rows, taking into account tied places (same dates)
SELECT
t.card_id,
SumAmount = SUM(amount),
FirstDate = MIN(t.created_at)
FROM (
SELECT *,
rn = DENSE_RANK() OVER (PARTITION BY t.card_id ORDER BY t.created_at)
FROM dbo.Transactions t
) t
WHERE t.rn = 1
GROUP BY t.card_id;
If the dates are actually dates and times, and you want to sum the whole day, change t.created_at to CAST(t.created_at AS date)
Try this:
/*
CREATE TABLE dbo.Transactions
(
card_id INT,
amount MONEY,
created_at DATE
);
INSERT INTO dbo.Transactions (card_id, amount, created_at)
VALUES (1, 500, '2016-01-01'),
(1, 100, '2016-01-01'),
(1, 100, '2016-01-01'),
(1, 200, '2016-01-02'),
(1, 300, '2016-01-03'),
(2, 100, '2016-01-04'),
(2, 200, '2016-01-05'),
(3, 700, '2016-01-06'),
(1, 100, '2016-01-07'),
(2, 100, '2016-01-07'),
(3, 100, '2016-01-07');
*/
WITH FirstDatePerCard AS
(
SELECT
card_id,
FirstDate = MIN(created_at)
FROM
dbo.Transactions
GROUP BY
card_id
)
SELECT DISTINCT
t.card_id,
SumAmount = SUM(amount) OVER (PARTITION BY t.card_id),
FirstDate = f.FirstDate
FROM
FirstDatePerCard f
INNER JOIN
dbo.Transactions t ON f.card_id = t.card_id AND f.FirstDate = t.created_at
You'll get an output something like this:
card_id SumAmount FirstDate
--------------------------------
1 700.00 2016-01-01
2 100.00 2016-01-04
3 700.00 2016-01-06
Is that what you're looking for??
UPDATE: OK, so you want to sum the amount only for the first_date, for every card_id - is that correct? (wasn't clear from the original question)
Updated my solution accordingly
I want to see user statics, so I made query:

It's working. Here is the result:
But I want to make a pivot by Months (last 6 months)...
WITH MONTHS AS
(
SELECT ADD_MONTHS(TRUNC(SYSDATE,'MONTH'),-LEVEL+1) AS MONTH,
DECODE(LEVEL,1,'Akt_mesiac','minuly_mesiac'||(LEVEL-1)) AS MONTH_NAME FROM DUAL CONNECT BY LEVEL <=7)
SELECT

FROM (
SELECT

FROM MONTHS M
JOIN obj_odb_l l ON M.MONTH=TRUNC(l.datum_p,'MONTH')
) PIVOT
( SUM(CNT)
FOR MONTH_NAME IN
('Akt_mesiac' AS Akt_mesiac,
'minuly_mesiac1' AS minuly_mesiac1,

'minuly_mesiac6' AS minuly_mesiac6)
);
Table: obj_odb_l l ->date column -> l.datum_p -> trunc(l.datum_p,'MONTH')
How can I make a pivot table ?
Consider adding the month expression, TRUNC(l.datum_p,'MONTH'), into above aggregate query. Then run the query as another CTE in pivot query for JOIN in pivot's data source.
WITH MONTHS AS (
SELECT ADD_MONTHS(TRUNC(SYSDATE,'MONTH'),-LEVEL+1) AS MONTH
, DECODE(LEVEL,1,'Akt_mesiac','minuly_mesiac'||(LEVEL-1)) AS MONTH_NAME
FROM DUAL CONNECT BY LEVEL <=7
)
, AGG AS (
-- SAME AGGREGATE QUERY WITH TRUNC(l.datum_p,'MONTH') ADDED TO SELECT AND GROUP BY
-- POSSIBLY ADD WHERE CONDITION FOR LAST SIX MONTHS (IF DATA GOES BACK YEARS)
)
SELECT *
FROM (
SELECT AGG.partner
, AGG.prod_man
, AGG.obj_pocet
, AGG.nedod_pocet
, AGG.'%' AS PCT -- AVOID SPECIAL CHARS AS NAME
, M.MONTH_NAME
FROM MONTHS M
INNER JOIN AGG
ON M.MONTH = AGG.MONTH -- NEW FIELD USED FOR JOIN
)
PIVOT
( SUM(PCT) -- ONLY PIVOTS ONE NUM AT A TIME
FOR MONTH_NAME IN
('Akt_mesiac' AS Akt_mesiac,
'minuly_mesiac1' AS minuly_mesiac1,
'minuly_mesiac2' AS minuly_mesiac2,
'minuly_mesiac3' AS minuly_mesiac3,
'minuly_mesiac4' AS minuly_mesiac4,
'minuly_mesiac5' AS minuly_mesiac5,
'minuly_mesiac6' AS minuly_mesiac6)
);
I have a table in SQL Server with the following format
MType (Integer), MDate (Datetime), Status (SmallInt)
1, 10-05-2018, 1
1, 15-05-2018, 1
2, 25-3-2018, 0
3, 12-01-2018, 1
....
I want to get the MIN MDate for specific MTypes for future dates. In case there isn't one, then the MType should be returned but with NULL value.
Here is what I have done until now:
SELECT m.MType,
MIN(m.MDate)
FROM MyTypes m
WHERE m.MType IN ( 1, 2, 3, 4)
AND m.MDate > GETDATE()
AND m.Status = 1
GROUP BY m.MType
Obviously, the above will return only the following:
1, 10-05-2018
Since there are any other rows with future date and status equals to 1.
However, the results I want are:
1, 10-05-2018
2, NULL
3, NULL
4, NULL //this is missing in general from the table. No MType with value 4
The table is big, so performance is something to take into account. Any ideas how to proceed?
One way is to join the table to itself and filter the date in the ON clause.
SELECT a.Mtype, MIN(b.MDate)
FROM MyTypes a
LEFT JOIN MyTypes b
ON a.MType = b.MType
AND b.MDate > GETDATE()
AND b.Status = 1
WHERE a.MType IN ( 1, 2, 3)
GROUP BY a.MType
Here's a Demo.
I don't know what is logic behind but it seems to use of look-up tables
SELECT a.MType, l.MDate
FROM
(
values (1),(2),(3),(4)
)a (MType)
LEFT JOIN (
SELECT m.MType,
MIN(m.MDate) MDate
FROM MyTypes m
WHERE m.MDate > GETDATE()
AND m.Status = 1
GROUP BY m.MType
)l on l.MType = a.MType
Use a windows function and a union to a numbers table:
declare #t table (MType int, MDate datetime, [Status] smallint)
Insert into #t values (1, convert(date, '10-05-2018', 103), 1)
,(1, convert(date, '15-05-2018', 103), 1)
,(2, convert(date, '25-03-2018', 103), 0)
,(3, convert(date, '12-01-2018', 103), 1)
Select DISTINCT Mtype
, min(iiF(MDate>getdate() and status = 1, MDate, NUll)) over (Partition By Mtype) as MDate
from ( SELECT TOP 10000 row_number() over(order by t1.number) as MType
, '1900-01-01' as MDate, 0 as [Status]
FROM master..spt_values t1
CROSS JOIN master..spt_values t2
union
Select Mtype, MDate, [Status] from #t
) x
where MType in (1,2,3,4)
order by x.MType
I have attendance data list which is showing below. Now I am trying to find data by a specific date range (01/05/2016 – 07/05/2016) with total Present Column, Total Present Column will be calculated from previous present data (P). Suppose today is 04/05/2016. If a person has 01,02,03,04 status ‘p’ then it will show date 04-05-2016 total present 4.
Could you help me to find total present from this result set.
You can check this example, which have logic to calculate previous sum value.
declare #t table (employeeid int, datecol date, status varchar(2) )
insert into #t values (10001, '01-05-2016', 'P'),
(10001, '02-05-2016', 'P'),
(10001, '03-05-2016', 'P'),
(10001, '04-05-2016', 'P'),
(10001, '05-05-2016', 'A'),
(10001, '06-05-2016', 'P'),
(10001, '07-05-2016', 'P'),
(10001, '08-05-2016', 'L'),
(10002, '07-05-2016', 'P'),
(10002, '08-05-2016', 'L')
--select * from #t
select * ,
SUM(case when status = 'P' then 1 else 0 end) OVER (PARTITION BY employeeid ORDER BY employeeid, datecol
ROWS BETWEEN UNBOUNDED PRECEDING
AND current row)
from
#t
Another twist of the same thing via cte (as you written SQLSERVER2012, this below solution only work in Sqlserver 2012 and above)
;with cte as
(
select employeeid , datecol , ROW_NUMBER() over(partition by employeeid order by employeeid, datecol) rowno
from
#t where status = 'P'
)
select t.*, cte.rowno ,
case when ( isnull(cte.rowno, 0) = 0)
then LAG(cte.rowno) OVER (ORDER BY t.employeeid, t.datecol)
else cte.rowno
end LagValue
from #t t left join cte on t.employeeid = cte.employeeid and t.datecol = cte.datecol
order by t.employeeid, t.datecol
You could use a subquery to calculate TotalPresent for each row:
SELECT
main.EmployeeID,
main.[Date],
main.[Status],
(
SELECT SUM(CASE WHEN t.[Status] = 'P' THEN 1 ELSE 0 END)
FROM [TableName] t
WHERE t.EmployeeID = main.EmployeeID AND t.[Date] <= main.[Date]
) as TotalPresent
FROM [TableName] main
ORDER BY
main.EmployeeID,
main.[Date]
Here I used subquery to count the sum of records that have the same EmployeeID and date is less or equal to the date of current row. If status of the record is 'P', then 1 is added to the sum, otherwise 0, which counts only records that have status P.
Interesting question, this should work:
select *
, (select count(retail) from p g
where g.date <= p.date and g.id = p.id and retail = 'P')
from p
order by ID, Date;
So I believe I understand correctly. You would like to count the occurences of P per ID datewise.
This makes a lot of sense. That is why the first occurrence of ID2 was L and the Total is 0. This query will count P status for each occurrence, pause at non-P for each ID.
Here is an example
I have a table which contain the following columns:
plantId (pk)
unitId
maxCapacity
numberOfPlants
geographicalArea
agreementStart
agreementEnd
plantType
The table contain the following data:
1, A1, 10, 1, 3, 2013-01-01, 2013-12-31
2, A2, 10, 1, 3, 2013-01-01, 2013-12-31
3, A1, 10, 1, 3, 2013-03-01, 2013-12-31
I would like to query my table like this:
SELECT DISTINCT
plantType,
geographicalArea,
sum(maxCapacity) as maxCapacity,
sum(numberOfPlants) as numberOfPlants,
count(unitId) as idCount
FROM
tbl_plant
WHERE
(agreementStart <= '2013-11-28' AND
agreementEnd >= '2013-11-28') AND
plantType <> '0' AND
plantType = '2' AND
geographicalArea = '3'
GROUP BY
plantType, geographicalArea
This query works well as long as there is only one unique unitId returned per row in the resultset. However, if the same unitId is returned a second time (see A1 above), I do not want the sum(maxCapacity) and sum(numberOfPlants) include the sum a second time since it has already included it.
Any ideas of how I'd need to change this query?
Use inner query to get rid of duplicates
SELECT plantType, geographicalArea, sum(maxCapacity) as maxCapacity, sum(numberOfPlants) as numberOfPlants, count(unitId) as idCount
FROM tbl_plant
WHERE plantId in (
SELECT MAX(plantId)
FROM tbl_plant
WHERE (agreementStart <= '2013-11-28' AND agreementEnd >= '2013-11-28')
AND plantType <> '0'
AND plantType = '2'
AND geographicalArea = '3'
GROUP BY unitId
)
GROUP BY plantType, geographicalArea
